To all whom it may concern."

Be it known that I, RAYMOND Erin- Hana, a citizen of the United States, and a resident of Edgewood Park,'in the county of Allegheny and State of Pennsylvania,

have madea new and useful Invention in Marine 'lurblne Installation, of which the following is a specification.

This invention relates to turbine installationsand has for an object to produce a new and improved "arrangement of turbine and condenser which is especially adapted to be employed on ships.

A further object of my invention is to produce a marine turbine installation which is more compact and efiicient than other similar installations now in use and known to me.

A further object is to produce a geared turbine'insta llation in which new and 'im-" proved means are employed for mounting the turbine and condenser so that space is conserved and the condenser shell is free to expand and contract without affecting the operation of the turbine.

These and other objects are attained by' means of a turbine installation embodying the features herein described and illustrated in the drawings accompanying and forming a part hereof.

My invention contemplates a compacf power developing installation in which the turbine is mounted directly on the condenser and the latter is hung or supported from above so that it is free to expand downward without affecting the alinement of the turbine. WVith such an arrangement the expansion joint between the turbine and condenser is eliminated and the length of the exhaust passages is reduced to a minimum and only one joint is necessary in the connection between .the turbine and the condenser. In

geared installations the driving pinion of the gearing is preferably placed above the driven gear so that the turbine, which is of- Specification of Letters Patent.

Fig. 2 is a diagrammatic end view of the apparatus illustrated in Fig. 1.

T heapparatus illustrated includes a turbine 5, a condenser 6 located below the turbine and into which the turbine 5 exhausts,

and a reduction gearing 7 located astern the turbineand the condenser, and operatively connecting the turbine 5 to a propeller shaft 8. As shown, the installation is locatedin the hull 9 of a Ship, a Portion only of hull structure being shown 4 The turbine 5 is shown mounted directly on and supported by the condenser 65. The latter is suspended from a structural franiey 10, or in any other suitable manner, so thatthe points of support are substantially in the plane of the connection between the turbine and the condenser. Under such condition the condenser forms a rigid and immobile support for the turbine, whereas the condenser shell, hanging below the condenser support, is free to expand and contract with changes of temperature.-

As shown, the turbine 5 occupies a position considerably above the propeller shaft 8, consequently the gearing 7 is arranged with the pinion above the gear so that the pinion shaft 11 is in alinement with the rotor ofthe turbine 5.

The installation illustrated is unusually compact and simple as it is only necessary to properly suspend the, condenser and to thenmount the turbine directly on it. A separate foundation or support for the turbine therefore unnecessary, the connections be tween the turbine and the condenser are-"f .short, with but one simple connecting joint,

and the amount of space required for the installation is reduced to a minimum.

, While I have described and illustrated but one embodiment of my invention, it will be apparent to those skilled in the art that various changes, modifications, additions and omissions may be made in the apparatus illustrated without departing from the spirit and scope of the invention as set forth by the appended claim.

What I claim. is:

' A turbine installationcomprising a condenser provided with a supportin exhaust connection for the turbine, a tur ine supported by the said exhaust connection and exhausting therethrough into the condenser,

i tion' and the turbine casing and so that the I 'condenser and the turbine. casing are free to expand lndependently on opposite sldes of "Wltnessz end means for-supporting the condenser so 'In testimony whereof I have hereunto that the points of support are substantially subscribed my name. this 17th day .of
